Local great white shark sightings on the rise

SAN DIEGO- A rash of great white shark sightings in San Diego waters has surfers, swimmers, and a fisherman wondering what’s going on.

Lobster divers wonder if the recent population growth in the sea lion and seals have started to draw sharks closer to shore.

“It’s possible the white shark population is on the rise, but I don’t think La Jolla’s pinniped (population) growth has any significant effect on shark patterns,” said Heidi Dewar a shark expert from the National Oceanic Atmospheric Administration.

“It’s hard to get into the mind of a shark. The great white shark feeding grounds at Guadalupe Island  have tens of thousands of pinnipeds to dine on. La Jolla has a few hundred,” Dewar said.

    Sea Lion over population in the area is the reason for the shark boom. Sea world and other "do gooders" need to stop rescuing the seal pups that are abandoned by their mothers and let nature run it's course. It's for the greater good.

    It's funny to see how the size of the Great White shark that was video taped by the fisherman went from 14' in the original news casts and now it's up to 18'. And as for Dewar's statement here… “It’s hard to get into the mind of a shark. The great white shark feeding grounds at Guadalupe Island have tens of thousands of pinnipeds to dine on. La Jolla has a few hundred,” … perhaps she needs to familiarize herself with her local area… there are a few hundred harbor seals counted at the Children's Pool Beach and the beaches to the north and south alone… and then there's the sea lions at the cove… and of course there's more to La Jolla than those 2 spots. Is the documented seal population the cause for increased shark sightings?… who knows, but hopefully our news casting and professionals can start by accurately representing what is known for a change.

    At last count, 2012, there were more than 400,000 pinnipeds in the State of California with more than 34,000 harbor seals pupped at San Miguel Island last year….I'm not 100% sure, but I do not believe there are tens of thousands of pinnipeds at Isla de Guadalupe Island. I have visited that location many times and although there are pinnipeds that utilize the island there numbers are far less than tens of thousands. I have posted several white shark bitten pinnipeds from the La Jolla Shores, Children's Pool Area on my web sites news page over the past several years. White sharks have been utilizing the La Jolla area for decades. Population dynamics of humans and sharks are primarily responsible for the increased sightings……numbers of adult white sharks are unknown at present…..only estimates based on models have been proposed.
